The In the accompanying drawings: .35 underside of theflanges I'I provide, along their Fig. 1 is a View in plan of a screwconveyer outer edges, downwardly facing abutments or including aconveyer housing embodying the cam means 20 that extends substantiallythe full invention; length of each of the conveyer trough sections Fig.2 is a view in section on a larger scale, the I2 and along each sidethereof. view being taken on line 2-2 of Fig. 1; U The top or open sideof the conveyer trough or Fig. 3 is a view in section on a larger scalehousing portion IB is closed by a plurality of of a fragment of aconveyer housing seen in Cover plates 2I which preferably are notched atFigs. l and 2, the view being taken on line 3-3 their ends, as seen inFig. 4 of the drawings, to of Fig, 1; f provide a space or opening 22between them.

Fig. 4 is a view in plan showing fragments of 5 The longitudinallyextending side edges of each adjacent conveyer housing cover plates anda of the cover plates 2l are bent downwardly to bar or strip thatinterconnects them, a portion form flanges 23, as seen in Fig. 2 of thedrawings, of said bar or strip being broken away to show that extenddownwardly, transversely and at one more clearly the construction of theadjacent side of the longitudinally extending downwardly ends of saidcover plates and 0 facing abutments or cam means 20 of the trough Fig. 5is a view on a larger scale of a fragment sections I2.

of the conveyer housing as seen in Fig. 2 and The flanges Il and 23 areintegral with the showing particularly the structure of an adtroughsection I2 and the cover plate 2I, respecjustable cam mechanism carriedby the conveyer tively, as seen in the drawings, but it is to be housingcover. understood that they may be formed of separate pieces, such asangle members riveted or otherwise attached to the trough sections |2and cover plates 2|, if desired. Each cover plate 2| spans and closesthe open top or side of one of the conveyer trough sections |2 and itseats upon the gasket |9 at each side thereof to seal substantially thecover and the trough sections together.

As seen in Fig. 2 of the drawings, the righthand downwardly extendingflange 23 of the cover plate 2| has secured thereto a plurality ofrivets 24 having cone shaped heads 25 thatjorrn upwardly facingabutments or cams that' cooperate with the downwardly facing abutmentsor cams 20 on the adjacent iiange .|'lzofthe conveyor trough section |2.The opposite or left-hand downwardly extending ange 2.3 of thecoverplate 2| has welded thereto a plurality o' nuts 26 each of whichreceives a screw 21, the headotwhich is cone shaped like the heads 25 ofrivets 24. The headso screws 2l form upwardly facingabutmentsor camsvthat cooperate with the ,down-i wardly acing cani or abutment 2-ofthelflange |1'lfadjaeent thereto. Each scr-ew 2ly is,preferablyVKslcttedgin itsendtorreceive a screwdriver by which the; screw and itsintegral head or cammay be adjusted to and from the adjacent flange'ofrthe troughrsection I2.

Fromthe-description thus far given it will be seen that each of theconveyer cover sections 2| includes: along each;A side thereof aflangerthat extends transversely of theadjacent longitudinally extendingsideflange Il of the conveyer troughsectionl |;2` and that each ofthedownwardly enV tendingriiangescarrycam means that cooperate with anyadjacent ange 2 3 of thevconveyer trough section I2. When the screws 2-are adjustedziinwardly'- or toward thev conveyer trough section |r2ztheupwardly facing cam surfaces providedby theconeshapedheads or upwardlyfacing .cam surfaces 25` ofthe rivets 24 and screws2-1 cooperate withthe downwardly facing abutments Zetacam thecover platea 2| toqthelef-tand clamp it. downwardly upon the: gaskets |9to the-,flanges |T to sealYsubstantially thecover plate-2d to the conveyer trough sectionv l2. Thecover plates 2`|` may be removed readily from the conveyer troughsections l2 by the mere lexpedient of loosening the screws 2 and liftingthe cover plates 2| from the trough` sections l2.

The cover plates or sections, 2| alepreferably slightly spaced from eachother atV their adjacent` ends although. they may abut; eachother,andthrough. the spaceV or opening 22 there is; ex,- tendecl '1T-headedbolts 2B that secure strip 29. that interconnects the adjacent coverplates2| and rests upon a, strip. 390i gasket material of felt, rubberor the like. Eachbar o1',- strip 29 has substantially the same contoun;as seen in Fig. 2, as the cover plates2| and. it is of such size astont-over the adjacent coverl plates 2| and gasket or sea-1 strip 39 andeach is flanged at its ends to overlap the adjacent downwardly extendingflanges 23 of the cover plates 2|.

Each of the bars or strips 29 isprovided with three of the Theaded bolts28 which extend herethrough and are provided with gaskets 3|, washers3?.A and nuts 33.

In order to place each bar or strip 29 and gasket 3|! upon the housingportion lll to close substantially one of the spaces or openings 22 andto seal the adjacent cover plates 2|v together it is only necessary thatthe heads ofthe T-headed bolts 29l be aligned so that they extendtransversely of the conveyer trough l0 and: longitudinally4 of one abary or Ll i) of the spaces or openings 22 whereby their heads may passthrough the latter between adjacent cover plates 2|. With the bolts 28thus alignedy the bar or strip 29 and gasket 30 are placed over thespace or opening 22, and the heads of the T-headed bolts 23 are passedthrough the space or opening 22.

With the bar or strip 29 and gasket 30 thus positioned. the T-headedbolts 28 arefrotated 90 so that their heads extend longitudinally of theconveyer trough |0 and transversely of the space or opening 22 andoverlap the edges of the adjacent cover plates 2|. The nuts 33 are nowtightened and the bar or strip 29 is secured in position'. In order toremove the bar or strip 29 and gasket 30 from the conveyer housing I0the nuts 33 are loosenedk the bolts 28 are rotated so that their headsare aligned with the space or opening 2.2, and the bar or strip 29 andgasket 30 are lifted therefrom.

Erom the foregoing description itvwill be seen thatI thisinventionprovides a very simple andinexpensive conveyerthroughconstruction thatine cludes a plurality of covers or cover sectionsthatmaybe readily placed thereonv and removed therefrom by thesimple removalof the bars or st-rips29I and by theloosening ofthecam means or screws21.

It will also=bel seen that the 'If-headed bolts7 nuts 331, washers32-andgaskets 3|- and 30 need never-be removed from the-bars or strips29f andtherefore will not inadvertently become lost therefrornwhen the barsor'strips are removed from. the covers. It will also be seen that thecam screws 21' are-backed outwardly and against the nuts 26 whenl theconveyer cover plates 2|- are to be removed from the conveyer troughIl)` and that therefore-these screws 27E needl notbe separated fromthecover plates; 2|. Gaskets |29 maybe attached to eitherl the coverplates 2| or the'iianges: and. preferably to the cover plates2|5as.by,cement so that when the cover plates 2| are removed from theconveyer troughsection |;2: the gaskets. |.9-. will remain attached tothem.

Asshownin Fig. l of.' the drawings there'is a rivet. 24 spaced oppositeeach ofthe-cam screws 2-`|J and while this arrangement is preferred itis to be. understood that other arrangements may be itihzed', and thatany desired number ofthe rrllviee 24 or cams 25 and screws 2l' may bepro- O bviously those skilled in the art may make various. changes inthev details and arrangement of parts without departing from the spiritandV scope of the inventiony as deiined by the claims heretoappended,and applicant therefore Wishes nottobe vrestrictedto the preciseconstruction herein disclosed.
